Commission hears CSO and pump‑station progress; 72‑inch interceptor and Bennett Street pipeline moving forward
Summary
Staff reported completion of one pump station pending National Grid electrical hookup and ongoing installation of a 72‑inch interceptor on Bennett Street; about half of the 72‑inch pipe work is completed monetarily but progress exceeds 80% on physical installation for several segments.
The commission received a construction progress update on combined sewer overflow (CSO) work and pump station phases. Anthony, a staff member, said one pump station is built but remains offline while National Grid completes an electrical hookup scheduled around the 20th of the month; testing and commissioning are expected after the hookup and the station likely will be operational in about two months.
Anthony said contractor Gioso is installing 72‑inch pipe down Bennett Street and that crews have installed approximately 350 of an estimated 1,000 feet; the 72‑inch line remains the last major installation. He also said crews completed about 500 feet of in‑situ lining on the western interceptor. “That work is complete,” Anthony said, and added that while the 72‑inch pipe accounts for a large share of project cost, installation progress in feet is ahead of the monetary percent complete.
Staff noted outstanding dependencies on National Grid and earlier coordination issues with Comcast at specific pump stations; where utilities have delayed work, the construction crews have shifted to other tasks. Commissioners asked questions and expressed frustration with utility coordination; one commissioner said, “National Grid's been a problem.”
The update included schedule expectations: once National Grid finishes de‑energizing lines and performs hookups, crews will complete the electrical work and testing followed by startup. Staff estimated roughly two months until the newly completed pump station is fully operational. No formal action or vote was taken on this item.
Ending — Staff will continue to monitor utility coordination and report on the hook‑up and commissioning schedule at subsequent meetings.
